I'm new to the list. Hello. I just googled and tried some general news lists. There is hard to compose good question to google, cause shutdown and poweroff are standard ups jobs. Then. I've upgraded some computer Centos 5.3 to Centos 6.1. It is powered with Powercom BNT-400AP ups. A problem is, when I try to start upsdriver - powercom. While connecting to the ups (via ttyS) it

Fix two command-line parsing problems: - the argc check is wrong: it must be provided with the frontend device - the ro/rw mode is optional, so default to rw if it is absent Also, update the usage message accordingly.

Hello. I''ve built a kernel from git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux-2.6.git (Date: Fri Nov 19 19:46:45 2010 -0800) and got a kernel oops when tried to access to unplugged, but mounted external usb storage formatted with JFS. Steps to reproduce: mkfs.jfs /dev/sdb1 (unpluggable USB hard drive) mount /dev/sdb1 /mnt/drive cd /mnt/drive touch test sync

I am running Xen 4 and want users to be able to install arbitrary HVM images. We want both PV and emulated drivers to appear. The reason for this is for compatibility with images that were prepared for Xen 3.3, which assume emulated devices exist at boot time (particularly for running the boot loader). If I do not specify on the boot line xen_emul_unplug=never, then under some guest OS''s

Package: logcheck Version: 1.2.63 Severity: minor Tags: patch Hi, There was recently a modification to filter acpid stuffs. But there are still things not filtered by logcheck. When I unplugg, then plug back my battery, I get following notifications: System Events =-=-=-=-=-=-= Nov 8 21:41:31 morpork acpid: received event "ac_adapter AC0 00000080 00000000" Nov 8 21:41:31 morpork

Hi, I''ve been touring XCP and making my way around it for the last few days, and am having problems with some reasonably straightforward actions. I''ve poured a several hours into different ways of resolving the issue, but am coming up short. Here''s the main issue. The following command (plugging in a VBD to the dom0 VM), when, run, hangs for several minutes, and then

...is patch (PageOffline() + refcount == 0)? e) How to make __offline_isolated_pages() succeed? Like I propose in this patch (PageOffline() + refcount == 0)? In summary, is what you suggest simply delaying setting the reference count to 0 in MEM_GOING_OFFLINE instead of right away when the driver unpluggs the pages? What's the big benefit you see and I fail to see? -- Thanks, David / dhildenb

Changes since v1: - Fix a double-free bug introduced by v1, pointed out by Stefano where internal pointer was being passed back to caller from libxl_create_stubdom() 8<---------------------------------------------------------------------- Currently scratch variables allocated by libxl have the same lifetime as the context. While this is suitable for one off invocations of xl. It is not

The series introduces auto-generation of the type definitions used in the libxl interface followed by auto-generation of a destructor function for each type. In the future it may be possible to use the related data structures for other purposes, for example auto-generation of the functions to marshal between C and language binding data types. tools/_libxl_types.h should be identical both before

Hi, this is an idea that is based on Andrea Arcangeli's original idea to host enforce guest access to memory given up using virtio-balloon using userfaultfd in the hypervisor. While looking into the details, I realized that host-enforcing virtio-balloon would result in way too many problems (mainly backwards compatibility) and would also have some conceptual restrictions that I want to avoid.

Btw, I am thinking about the following addition to the concept: 1. Add a type to each virtio-mem device. This describes the type of the memory region we expose to the guest. Initially, we could have RAM and RAM_HUGE. The latter one would be interesting, because the guest would know that this memory is based on huge pages in case we would ever want to expose different RAM types to a guest (the

Hey, I thought there was supposed to be an ability for domU''s to be put into a hibernated state (E.g. current running tasks and memory) when dom0 is shutdown or rebooted. When I look in my /etc/default/xendomains file, I have the variable''s "XENDOMAINS_SAVE=/var/lib/xen/save" and "XENDOMAINS_RESTORE=true". However, when I reboot, I always have to restart my
